Title: Magneto-optical recording medium
Inventor: MATSUBAGUCHI SATOSHI
IPC: G11B11/10
Filed: 1990-05-22
Abstract: PURPOSE:To obtain the recording and reproducing characteristics of the low dependency on a linear speed by specifying a recording layer and a metallic reflecting layer. CONSTITUTION:The recording layer is constituted of the thin film of an amorphous alloy of a DyFeCo system and the thermal conductivity of the metallic reflecting layer is specified to >=25(W/m k). The dependency of the sensitivity on the linear speed is lowered by making the thermal conductivity of the metallic reflecting layer as relatively high as >=25(W/m k). The Curie temp. (Tc) is lowred by introducing the Dy into the amorphous alloy compsn. of the recording layer, by which the degradation in the sensitivity by the increased thermal conductivity of the metallic reflecting layer is prevented. The dependency of the sensitivity on the linear speed is, therefore, lowered even if the rotating speed of a drive increases from a low speed to a high speed.
